Hi,
Thanks so much for getting back to me. I could group the classes in a group of 9 without any issues but when I grouped them as 10, the classes became greyed out and could not be selected.
However, upon your advice, I made the “past events bookable” and now the group of 10 can be booked. Even though the dates are 4th Feb 2019 to 12th April 2019.
It works now and that’s the main thing. Thanks for your prompt response!
